This easy and delicious Apple Plum Crisp is the perfect transitional dessert from summer to fall. It marries the two seasons with beautiful fruit and the warmth of apple pie spice. Topped with a nutty and buttery pecan crisp crumble.
First, make the crumble by mixing together the flour, rolled oat, brown sugar, salt and apple pie spice in a medium mixing bowl.
Add the cubed cold butter to the flour mixture and press the pieces with your fingers until all of the butter pieces are flattened and the mixture resembles slightly wet sand.
Toss the chopped pecans into the crumble mixture and refrigerate until ready to use.
Wash the fruits, peel and core the apples, remove the plum stones, and cut the fruits up into bite site pieces. Cut the plums into pieces slightly larger than the apples since they will soften faster when baked. Toss the cut up fruits with 1 tablespoon of lemon juice in a large mixing bowl.
In a small mixing bowl, stir together brown sugar, salt, apple pie spice and tapioca flour. Add the sugar mixture to the fruits and mixture to distribute evenly.
Transfer the fruit filling to a square baking pan, spread the crumble over the top evenly.
Bake for about 35 - 40 minutes until the filling is bubbly and the crumble is golden.
Notes
I used 2 medium apples and 4 large plums. If your plums are smaller, use more of them. You’ll want a total of 2 lbs of fruits.
If at any point, your crumble starts to brown too much, you can tent the baking pan with a large piece of foil and continue baking.
